The Blair Witch Project was the most profitable movie ever made.
And Titanic was the highest grossing, though both sucked awfully.
(And actually, I think Deep Throat made a higher return on investment than Blair Witch.)
Class 1/ "The Green Slime": Went with my family to the Chillum Drive-In for a Dusk to Dawn Show. "Slime" is one of the worst 1960s Italian/American pieces of really bad Sci-Fi.
Also "The Paper Chase": Saw it with my girlfriend and kept wondering why I was there. Since I knew as a teen that college wasn't going to be in the cards. Especially with a Professor like John Houseman.... "The Sterile Cuckoo" was so much better!
Class 2/ "X-Tro": Bought it on a whim and a brief review in "Twilight Zone" magazine. Should have saved my money.
Also, the little known "The Spook Who sat By The Door". A great novel about a black CIA agent who resigns a few years after training. Returns to Harlem and begins training (With or without his superiors aegis) black gang members on the finer arts of sniping, bombs and other insurgencies for the up coming Revolution.
Great little book. God awful movie!
